A one-time protege of Vincent “Vinny Gorgeous” Basciano’s yesterday fingered the former acting boss of the Bonanno crime family as a shotgun-wielding killer.

Bonanno capo-turned-canary Dominick Cicale testified about two murders he committed with his former mentor – and one he prevented.

The hulking Cicale, 39, said he and Basciano were the two gunmen who murdered Frank Santoro as he walked his Doberman pinscher in the Throgs Neck section of The Bronx in February 2001.

“I was one of the shooters,” Cicale said during testimony in Brooklyn federal court, noting that he carried a six-shooter while Basciano was toting a “pistol grip shotgun.”

When asked why the man he described as a “junkie” was murdered, Cicale said, “Frank Santoro was supposedly looking to kidnap one of Vinny Basciano’s sons.”

He explained in grisly detail how he and Basciano, 46, jumped out of an idling car and started blasting bullets at him.

“I said, ‘Excuse me,’ and as he turned around, I started firing shots at his head, and Vinny started firing also.”

Basciano continued to unleash his wrath on Santoro, even after his body hit the ground, Cicale said.

Basciano shook his head in disgust at the sight of his former charge on the witness stand.

Cicale also testified about how Basciano brought him along over the years, helping him become a “made” member of the crime family, and teaching him tricks of the trade such as how to avoid being followed in a car and advice on what to listen to while driving.

“I should listen to 1010 [WINS] and news channels because music dulls the senses,” Cicale said he was instructed.
